This ConCar AVX13 V-belt is designed for a drive system with a length of 1450 mm and a cross-section of 13 × 10 mm. The belt connects driving and driven pulleys and is suitable – depending on the specific system – for driving vehicle auxiliary components.
The open-flanked, toothed underside enhances flexibility as it rotates over the pulleys. The belt is made of a rubber compound with reinforced polyester/glass fiber tensile members. It is heat- and oil-resistant as well as antistatic. The profile is designed for compact belt drives where the corresponding AVX cross-section is specified. Depending on the design, the belt can be used to drive fans, pumps, or other auxiliary components.
The additional reference lengths Lw = 1,432 mm and Li = 1,387 mm simplify selection when the old belt marking uses a different length specification. These three length specifications describe different measurement references for the same belt: La is the outer length, Lw the effective length, and Li the inner length.
Before purchasing a new belt, compare the markings on your existing belt with the specifications provided by the vehicle or machine manufacturer. Also, check that the pulleys are clean, aligned, and free of sharp edges. Adjust the tension according to the manufacturer's instructions: too little tension can cause slippage, while too much tension puts unnecessary strain on the bearings and belt.
AVX13 is compared to XPA in the ConCar profile assignment. For alternative brands such as Gates, Optibelt, Continental, or Megadyne, the profile, reference length, and approval for the specific drive system must match; the brand name alone does not guarantee a suitable replacement.
Which length is crucial? Compare the specification AVX13 1450 La with the labeling of your previous belt and the manufacturer's documentation. Pay attention to whether it uses La, Lw, or Li.
Store the belt in a dry, cool place, protected from direct sunlight and without creases. Avoid contact with solvents or other substances that can damage rubber. A ConCar V-belt is supplied in the profile and length specified above.
